Classifying Luyten stars using an optical-infrared reduced proper-motion diagram.

SALIM S. and GOULD A.

Abstract (from CDS):

We present a V-J reduced proper-motion (RPM) diagram for stars in the new Luyten two-tenths (NLTT) catalog. In sharp contrast to the RPM diagram based on the original NLTT data, this optical-infrared RPM diagram shows distinct tracks for white dwarfs, subdwarfs, and main-sequence stars. It thereby permits the identification of white dwarf and subdwarf candidates that have a high probability of being genuine.
